| Sound Recording from species Altihoratosphaga nou (Hemp, 2006) (OSF) | 0:12 |
The song of A. nou was also composed of the two elements A and B. However, both elements were repeated several times to build one verse. On average, a verse of A. nou started with 13 ± 1.4 A elements, followed by 5 ± 0.9 B elements (range 9–16 A, 3–7 B; N= 58). The B elements mostly consisted of several impulse groups, but in some records they also consisted of single impulses (Fig. 3). The A elements were repeated at 3.6 Hz (a period of 275 ms), whereas within the B elements the impulse group period was 27 ms, on average.
